US Grid Hourly Operations & Power Plants (EIA)
Hourly US electric-grid demand, generation, fuel mix and interchange from the official EIA grid monitor, joined with the EIA-860/923 power-plant master library.
Part of the DataForge Open Data program — full production packages, free for academic and personal use. Canonical dataset page: [https://data.zalize.com/datasets/us-grid-hourly-power-plants-dataset](https://data.zalize.com/datasets/us-grid-hourly-power-plants-dataset)
Package inventory (original bundles, served from CDN)
All files are also served from the machine-readable open-data index: <https://dl.zalize.com/open-data> (per-package URL: https://dl.zalize.com/open-data/<package_id>).
Native parquet files (this repo)
Every table ships as snappy parquet under data/<tier>/ and renders in the Dataset Viewer above (one config per tier / table).
Original zip bundles (archive download)
The original production packages (csv + parquet + data dictionary + datasheet + license inside) are served from the DataForge open-data CDN (free, same license):
